JAMES E. ROBINSON, OF OOVINGTON, GEORGIA.

RAILROAD-FROG.

SPECIFICATION forming part of Letters Patent No. 633,158, datedSeptember 19, 1899.

Application filed May 15, 1899. Serial. No. 716,843. (No model.)

To to whom it Wen/y concern.-

Be it known that I, JAMES E. ROBINSON, a citizen of the United States,residing at Covington, in the county of Newton and State of Georgia,have invented certain new and useful Improvements in Railroad-Frogs; andI do hereby declare the following to be afull, clear, and exactdescription of theinvention, such as will en able others skilled in theart to which it appertains to make and use the same.

This invention relates to railroad-frogs; and it consists in the novelconstruction and combination of the parts hereinafter fully describedand claimed.

In the drawings, Figure l is a plan view of a frog and the railsadjacent to it. Fig. 2 is a cross-section through the wedge-shaped plateor double angle-bar.

A is the base-plate of the frog, and Bis its point. 7

O O are the rails of the main track, andD D are the rails of the sidetrack. The rails D and G converge toward the frog, and d c are railswhich rest on the base-plate A at one end and which form extensions ofthe rails I) and O. The rails 61 and c are arranged in front of thepoint B and form the approach or entrance to the frog. The pointB isprovided with guard-rails b in the usual manner.

E is a wedge-shaped plate or double anglebar provided with flanges e,which overlap the railsD, d, (l, and O, and j" are the usual jointbarsoutside the rails.

F are the fastening-bolts.

When the frog is a spring-frog, the guardrails b are formed integralwith or are secured to the rails 01 c, and the rails d and c are free toslide laterally upon the plate A, upon which they rest, as is usual in aspring-frog. The plate E is supported by the rails clear of the ground,so that it does not interfere with their lateral motion.

The wedge-shaped plate or double angle-bar has the double function ofkeeping the rails track-rails arranged in line with the said rails;

of a joint-bar supported by all the said rails and consisting of awedge-shaped plate provided with two flanges, said plate being ar:ranged above the base-flanges of the said rails and the said flangesbeing secured to the webs of the rails, substantially as described andshown.

In testimony whereof I affix my signature in presence of two witnesses.

JAMES E. ROBINSON.
